הפעלת Gemma באמצעות Gemini API

‫Gemini API מספק גישה מארחת ל-Gemma בתור API לתכנות שאפשר להשתמש בו בפיתוח אפליקציות או ביצירת אב טיפוס. ממשק ה-API הזה הוא חלופה נוחה להגדרה של מופע מקומי משלכם של Gemma ושירות אינטרנט לטיפול במשימות של AI גנרטיבי.

מודלים נתמכים

‫Gemini API תומך במודלים הבאים של Gemma 4:

  • gemma-4-31b-it
  • gemma-4-26b-a4b-it

בדוגמה הבאה אפשר לראות איך משתמשים ב-Gemma עם Gemini API:

Python

from google import genai

client = genai.Client()

response = client.models.generate_content(
    model="gemma-4-26b-a4b-it",
    contents="Roses are red...",
)

print(response.text)

JavaScript

import { GoogleGenAI } from "@google/genai";

const ai = new GoogleGenAI();

const response = await ai.models.generateContent({
  model: "gemma-4-26b-a4b-it",
  contents: "Roses are red...",
});
console.log(response.text);

REST

curl "https://generativelanguage.googleapis.com/v1beta/models/gemma-4-26b-a4b-it:generateContent" \
-H 'Content-Type: application/json' \
-X POST \
-d '{
  "contents": [{
    "parts":[{"text": "Roses are red..."}]
    }]
   }'

קבלת מפתח API

אפשר לגשת אל Gemini API בפלטפורמות רבות, כמו נייד, אינטרנט ושירותי ענן, וגם בשפות תכנות רבות. מידע נוסף על חבילות SDK של Gemini API זמין בדף הורדות של Gemini API SDK. מבוא כללי ל-Gemini API מופיע במאמר Gemini API quickstart.

העמקה

מודל Gemma 4 משתמש ב "תהליך חשיבה" פנימי שמבצע אופטימיזציה של ההיגיון הרב-שלבי שלו, ומספק ביצועים מעולים בתחומים שדורשים היגיון, כמו קידוד אלגוריתמי והוכחות מתמטיות מתקדמות.

ב-Gemma 4 אפשר רק להפעיל או להשבית את התכונה הזו, אבל כדי להפעיל אותה ב-API צריך להגדיר את רמת החשיבה ל-"high".

בדוגמה הבאה אפשר לראות איך מפעילים את תהליך החשיבה:

Python

from google import genai
from google.genai import types

client = genai.Client()

response = client.models.generate_content(
    model="gemma-4-26b-a4b-it",
    contents="What is the water formula?",
    config=types.GenerateContentConfig(
        thinking_config=types.ThinkingConfig(thinking_level="high")
    ),
)

print(response.text)

JavaScript

import { GoogleGenAI, ThinkingLevel } from "@google/genai";

const ai = new GoogleGenAI();

const response = await ai.models.generateContent({
  model: "gemma-4-26b-a4b-it",
  contents: "What is the water formula?",
  config: {
    thinkingConfig: {
      thinkingLevel: ThinkingLevel.HIGH,
    },
  },
});
console.log(response.text);

REST

curl "https://generativelanguage.googleapis.com/v1beta/models/gemma-4-26b-a4b-it:generateContent" \
-H 'Content-Type: application/json' \
-X POST \
-d '{
  "contents": [{
    "parts":[{"text": "What is the water formula?"}]
    }],
    "generationConfig": {
      "thinkingConfig": {
            "thinkingLevel": "high"
      }
    }
   }'

הבנת תמונות

מודלים של Gemma 4 יכולים לעבד תמונות, וכך לאפשר למפתחים להשתמש בהם בתרחישים רבים שבעבר דרשו מודלים ספציפיים לתחום.

בדוגמה הבאה תוכלו לראות איך משתמשים בקלט של תמונות Gemma עם Gemini API:

Python

from google import genai

client = genai.Client()

my_file = client.files.upload(file="path/to/sample.jpg")

response = client.models.generate_content(
    model="gemma-4-26b-a4b-it",
    contents=[my_file, "Caption this image."],
)

print(response.text)

JavaScript

import {
  GoogleGenAI,
  createUserContent,
  createPartFromUri,
} from "@google/genai";

const ai = new GoogleGenAI();

const myfile = await ai.files.upload({
  file: "path/to/sample.jpg",
  config: { mimeType: "image/jpeg" },
});

const response = await ai.models.generateContent({
  model: "gemma-4-26b-a4b-it",
  contents: createUserContent([
    createPartFromUri(myfile.uri, myfile.mimeType),
    "Caption this image.",
  ]),
});
console.log(response.text);
 ```

REST

IMAGE_PATH="cats-and-dogs.jpg"
MIME_TYPE=$(file -b --mime-type "${IMAGE_PATH}")
NUM_BYTES=$(wc -c < "${IMAGE_PATH}")
DISPLAY_NAME=IMAGE

tmp_header_file=upload-header.tmp

upload_url=$(grep -i "x-goog-upload-url: " "${tmp_header_file}" | cut -d" " -f2 | tr -d "\r")
rm "${tmp_header_file}"

# Upload the actual bytes.

  -H "Content-Length: ${NUM_BYTES}" \
  -H "X-Goog-Upload-Offset: 0" \
  -H "X-Goog-Upload-Command: upload, finalize" \
  --data-binary "@${IMAGE_PATH}" 2> /dev/null > file_info.json

file_uri=$(jq -r ".file.uri" file_info.json)
echo file_uri=$file_uri

# Now generate content using that file

    -H 'Content-Type: application/json' \
    -X POST \

      "contents": [{
        "parts":[
          {"file_data":{"mime_type": "'"${MIME_TYPE}"'", "file_uri": "'"${file_uri}"'"}},
          {"text": "Caption this image."}]
        }]
      }' 2> /dev/null > response.json

cat response.json
echo

jq -r ".candidates[].content.parts[].text" response.json

הוראות מערכת

אפשר להעביר הוראה למערכת כדי להגדיר את ההתנהגות של המודל:

Python

from google import genai
from google.genai import types

client = genai.Client()

response = client.models.generate_content(
    model="gemma-4-26b-a4b-it",
    config=types.GenerateContentConfig(
        system_instruction="You are a wise Kyoto tea master. Speak calmly and poetically, using nature metaphors. Keep answers under 3 sentences."
    ),
    contents="What is the purpose of the tea ceremony?"
)
print(response.text)

JavaScript

שיחות עם זיכרון

ה-SDK מספק ממשק צ'אט שעוקב אחרי היסטוריית השיחות באופן אוטומטי:

Python

from google import genai

client = genai.Client()
chat = client.chats.create(model="gemma-4-26b-a4b-it")

response = chat.send_message("What are the three most famous castles in Japan?")
print(response.text)

response = chat.send_message("Which one should I visit in spring for cherry blossoms?")
print(response.text)

JavaScript

import { GoogleGenAI } from "@google/genai";

const ai = new GoogleGenAI();
const chat = ai.chats.create({ model: "gemma-4-26b-a4b-it" });

let response = await chat.sendMessage({ message: "What are the three most famous castles in Japan?" });
console.log(response.text);

response = await chat.sendMessage({ message: "Which one should I visit in spring for cherry blossoms?" });
console.log(response.text);
